need new prop

[aussiejay]

I own a 1979 hunter 30, and need to replace the prop. I am running a ysm 12. Does anyone have the prop info including the pitch? The prop I am replacing is so far gone that the info stamped on it has corroded away, thanks for any help.

I also have a '79 hunter. I have my two blade in my basement and just looked- no stamping on the prop that I can determine but I pulled this from my file and it may assist you.

1979 Hunter 30' sloop　 (LOA 29'　 11")　 LWL 25' 9"　 Beam: 10'　 1"　 Draft 5' 4"　　 Displacement 9,700 lbs
Left Hand　rotation, 　one inch shaft,　　 Yamar YSM12
Engine Rating from manual: 10 hp @ 3000 rpm
********************************************************************
we would recommend a CS3LH12x7x1 for your installation. This is a Campbell Sailer, three blade, Left Hand rotation, 12" diameter, 7" pitch for a 1" shaft. This size is recommended to give you a good cruising rpm and still have reserve for head wind and seas.​

This propeller would cost you US$329.00 plus a shipping and handling fee of $35.00. It would take us 6-7 days to make this propeller and approximately 4-5 days for delivery

Good luck

I have a 78H30 that originally had the YSM12, the original prop was a 13x10LH 2 blade.

If you are looking for a new prop for one of these older Yanmars, take a look at a Campbell Sailor Prop. One of the fellow sailors in our marina got one and it has made all of the difference in the world on the performance compared to the OEM 2 blade.
